之前续写抖音开发者接入字节小游戏的缓存一下,现在说一下在 Windows 或者 Mac 如何用终端更换路径?
window:
（）比方说你的 window 目录下是这个路径:
第一:E:\project\Q1\trunk\client\src,然后你想切换到下一个路径的话,你可以这样子操作:
（）第二:E:\project\Q1\trunk\client\src> cd .\usersetting 然后回车,这里不会计较大小写
第三:你就可以在这个目录下执行你的脚本:E:\project\Q1\trunk\client\src\usersetting>
比如我是在E:\project\Q1\trunk\client\src\usersetting>下面有一个 js 脚本的那么你就可以执行下面这行操作,前提你要安装 node.js哦E:\project\Q1\trunk\client\src\usersetting> node .\imgmetachange.js然后回车即可;
然后就可以实现 window 的所有操作了,如果你想回到上一个目录的话.你可以这样子操作:
E:\project\Q1\trunk\client\src\usersetting>cd ..//(输入 cd..)两点就回车就可以回到上一个目录啦
E:\project\Q1\trunk\client\src>
===============以上是针对 window 操作系统的哈====================
macOS 系统操作如何下:
第一:zghMacBook-Pro:~ zghMacBookPro$ cd desktop//回车就可以指定你的桌面所有的内容,如果你想指定桌面的某一个文件
第二:你可以输入:zghMacBook-Pro:desktop zhengguohai$ cd 好了之后看然后回车就可以看见这个目录:zghMacBook-Pro:好看 zghMacBookPro$,如果你想在里面找某一个文件你可以这样子
第三:输入:zghMacBook-Pro:好看 zghMacBookPro$ ls回车就回出现很多文件夹,如果你想返回上一个目录的话,你可以输入:zghMacBook-Pro:好看 zghMacBookPro$ cd就会得到这个目录:zghMacBook-Pro:~ zghMacBookPro$ cd
===========以上就是针对 macOS 系统的目录如何更换目录的方法啦======
这个 imgmetachege.js 如下:

const path = require("path");
